How to define following function?
显示 更早的评论
I have two row vectors (say A1(1:5) and B1(1:5)). I wish to define a function 'a(t)' as given below. I am repeatedly getting error "Matrix dimensions must agree.". Can anyone help?
a=@(t) A1.*cos(B1*t) For ease: A=[1 2 3 4 5]; B=[9 1 2 6 4]

This code works just fine for me.
A1=[1 2 3 4 5];
B1=[9 1 2 6 4];
a = @(t) A1.*cos(B1*t);
What are you trying to do next? Can you post the code that actually gives the error?

Try something like this:
A = [1 2 3 4 5];
B = [9 1 2 6 4];
[A1,B1] = meshgrid(A,B);
a = @(t) A1.*cos(B1.*t);
The function works for single values of ‘t’. You will have to evaluate ‘a(t)’ in a loop, because it produces a matrix (obviously) for every value of ‘t’. I leave that to you, because I do not know what you want to do with your function.
